Personally, I strongly dislike abilities. I wish MUT was built in a way that didn’t require them.
We all are here because team building with player cards is fun but Imo there are two types of people that play MUT. Those that like the arcade style of gameplay and those that hope for a true simulation style gameplay. The way MUT and Madden in general is built kind of chokeholds it to be more of an arcade style that needs abilities to balance and spread the competency within cards and us as players. It‘s also a cheap way to try and hid the terrible animation based mechanics of this game.
Long story short I’ve come to the conclusion that Madden can’t make everyone happy with just one style of gameplay/game mode. I really hope they cater to both type of players next season but I highly doubt it because it would require a complete rebuild of the game and they haven’t done that since Madden 13.
